Thanks. Are there any good mods that enhance the singleplayer campaign?

Unfortunately, there is nothing that can be done to fix the damage in the vanilla single player campaign.

If your looking for a new single player experience, check out Movie Duels 2 (Recreates many of the epic lightsaber battles found in the movies, along with others such as Starkiller v Vader and the noncanon rematch between Obi-Wan and Maul that happens between RotS and ANH)
